BORIS JOHNSON rejected an invite yesterday to an urgent face-to-face meeting with union leaders to get London’s postponed Night Tube back on track.

Transport union TSSA general secretary Manuel Cortes extended a lifeline to the Tory mayor of London after negotiations over London Underground (LU) staff terms and conditions broke down and plans were suspended indefinitely.

The Night Tube, which was advertised across London to start on September 12 before the workers’ contracts were agreed, is not expected to start until next year at the earliest.
